It was previously observed [1] that the order of presentation of paired stimuli influenced the number of different responses in same-different tasks in speech synthesis evaluation. This paper investigates this phenomenon within the context of cognitive psychology and demonstrates that, as the cognitive psychology literature suggests, there is an effect relating to the prototypicality of the stimulus.
